Abstract
Description
Technical Field
[0001] The present invention relates to a hygroscopic pad that abuts on the body and can be used for sweating and the like.
Background Art
[0002] The sweating function is an important function for recovering the body temperature rising due to exercise or outside air temperature. However, when sweating大量に (大量に is incorrect Japanese here, should be 大量に), it may cause discomfort due to wet clothes and lead to the onset of sweat rash, so appropriate measures are necessary.
[0003] As measures from the perspective of clothing, there are cases of using mesh fabrics to improve ventilation and promote the evaporation of sweat, or using fabrics with fast drying properties. However, it is difficult to apply to all clothes. There is also a measure of attaching a highly hygroscopic pad under the armpits or on the back.
[0004] As such an example, Patent Document 1 discloses a multilayer structure sheet including an inner layer having an open cell structure and a sweat-absorbing layer having hygroscopicity laminated on the skin side of the inner layer, and a sweat-absorbing pad including a moisture-proof layer covering the clothing side of the inner layer. The inner layer has shrinkability accompanying pressurization and resilience accompanying pressure release while maintaining air chambers communicating with each other, and discloses a sweat-absorbing pad that promotes the intake and exhaust of air in the space sandwiched between the sweat-absorbing layer and the moisture-proof layer accompanying pressurization and pressure release to the inner layer, and states that it can continuously function the ventilation action and transpiration action inside and outside simultaneously with sweating.
[0005] However, the sweat-absorbing pad disclosed here has a complicated structure and there is room for improvement from the perspective of manufacturing cost.

Summary of the Invention
Problems to be Solved by the Invention
[0007] The object of the present invention, in view of the above-mentioned object, is to provide a moisture-absorbing pad that includes a moisture-absorbing sheet, comes into appropriate contact with the body, and can absorb moisture and water from the body surface with high efficiency. Means for solving the object
[0008] In order to solve the aforementioned problems, the inventors diligently studied the structure and material composition of moisture-absorbing pads, and as a result, arrived at the present invention.
[0009] To solve the above problems, a moisture-absorbing pad according to one aspect of the present invention is characterized in that a moisture-absorbing sheet is sandwiched between two pieces of fabric of a shape selected from a rectangle, a rectangle with at least one of C-chamfering and R-chamfering applied to its four corners, and a rectangle with at least one of a pair of opposing sides having an R shape, and the periphery and the center in the short side direction are sewn together to form a seam.
[0010] Furthermore, to solve the above problems, a moisture-absorbing pad according to one aspect of the present invention is characterized in that the shape of the fabric is an isosceles trapezoid in which the height is greater than the bottom base and at least one of the top base and bottom base is R-shaped.
[0011] Furthermore, a moisture-absorbing pad according to one aspect of the present invention, for solving the above problems, is characterized in that a first folded portion is formed by folding the opposing short-side portions of the moisture-absorbing pad toward the same plane, a second folded portion is formed by folding from the center of the folded edge of either one of the first folded portions toward the side where the first folded portion is formed, along a line at approximately 45° with respect to the folded edge, and further folding along the central seam in the short-side direction toward the first folded portion and the second folded portion.
[0012] As described above, the moisture-absorbing pad according to the present invention has a relatively simple structure, consisting of a sheet-like material with high moisture absorption sandwiched between two pieces of fabric cut to the required shape, and the edges and the center of the short side sewn together, thus making it possible to reduce manufacturing costs. Furthermore, although this moisture-absorbing pad can be used by applying it to the required part of the body in an unfolded state without folding, if it is folded as described above and attached, for example, to the connection point of a pair of bra cups, the so-called "cleavage," with the mountain fold of the central seam facing the chest, a force acts on the folded part to return it to its original shape, causing it to adhere appropriately to the surface of the body.
[0013] When used folded, the length of the first folded section should preferably be 20% to 40% of the length of the long side of the moisture-absorbing pad. The width of the folded section's length allows for adjustment to match the depth of the so-called "valley." More preferably, it should be 25% to 35%. This is because if it is less than 10%, the effect of the folding structure cannot be fully realized, and if it exceeds 40%, the length of the overlapping part of the two first folded sections becomes excessively large, increasing the thickness and reducing ease of handling.
[0014] Furthermore, because the moisture-absorbing pad according to the present invention has the above-described structure, it can be used not only in the cleavage but also by placing it between a shirt and the armpit, and in some cases, it can be placed in the part of shorts that comes into contact with the delicate area.
[0015] The material of the fabric used in the moisture-absorbing pad according to the present invention is not particularly limited, but considering moisture absorption, woven or knitted fabrics such as cotton, linen, silk, wool, and polyester are preferable. As the moisture-absorbing sheet sandwiched between the fabrics, a sheet containing a layer of water-absorbing polymers such as polyvinyl alcohol, polyethylene glycol, and sodium polyacrylate can be used, but if repeated use is anticipated, materials that can be dried, such as cotton, linen, silk, wool, polyester, rayon, microfiber, and nonwoven fabrics, are preferable. [Brief explanation of the drawing]

[Figure 2] This figure shows an example of a moisture-absorbing pad according to the present invention, with the first folding portion formed. [Figure 3] This figure shows an example of a moisture-absorbing pad according to the present invention, with a second folding section formed. [Figure 4] This figure shows an example of a moisture-absorbing pad according to the present invention in its usage state. [Figure 5] Front perspective view of an example of a moisture-absorbing pad according to the present invention in use. [Modes for carrying out the invention]
[0017] Next, embodiments of the present invention will be described. Figure 1 shows an example of a moisture-absorbing pad according to the present invention in an unfolded state, where Figure 1(a) is a front view and Figure 1(b) is a top view. This is an example using a fabric with an R-shaped upper and lower base of an isosceles trapezoid. As shown in this figure, the moisture-absorbing pad 1 has a moisture-absorbing sheet 3 placed in the area between the two pieces of fabric indicated by the dashed line in this figure, the periphery is sewn together with a seam 2a indicated by a dashed line, and the vertical center in the figure is sewn together with a seam 2b also indicated by a dashed line, so that the moisture-absorbing sheet 3 is fixed and does not shift position when folded, and therefore does not hinder folding.
[0018] Figure 2 shows an example of a moisture-absorbing pad according to the present invention, in which the first folded portions 5a and 5b are formed. The first folded portions 5a and 5b are formed by folding the valley fold portions 4a and 4b, shown by the dashed lines in Figure 1, in the same direction.
[0019] FIG. 3 is a view showing an example of the hygroscopic pad according to the present invention, in which second folding portions 6b, 6b are formed. The second folding portions 6b, 6b are formed by folding along the valley folding portions 4c, 4d shown by the two-dot chain line in FIG. 2 toward the first folding portion side. Note that the angle θ formed by the folding side of the second folding portion 5b and the valley folding portions 4c, 4d shown in FIG. 2 is approximately 45°.
[0020] FIG. 4 is a front view showing an example of the hygroscopic pad according to the present invention, in which the second folding portion is formed as shown in FIG. 3, in a state of use by folding the pad at the center in the vertical direction of the figure toward the side where the second folding portion is formed. FIG. 5 is a front perspective view showing an example of the hygroscopic pad according to the present invention in a state of use.
[0021] The hygroscopic pad according to the present invention can be used by being placed in the valleys of the chest or under the armpits, etc., in a deployed state or in a folded state as shown in FIGS. 4 and 5. In the folded state, it adheres to the part of the human body where it is placed with a force that tries to return to its original state and quickly absorbs sweat, thus helping to spend the hot season comfortably.
[0022] As described above, according to the present invention, it is possible to provide a hygroscopic pad that has a simple structure, abuts on the human body with an appropriate force, and can absorb moisture and water on the human body surface with high efficiency. The present invention is not limited to the above-described embodiment, and includes, for example, various modifications and corrections that can be conceived by those having ordinary knowledge in the field of the present invention, such as changing the shape of the cloth, as long as they do not depart from the gist of the present invention.
